as a WordPress expert I’ve been working with websites for years and I can tell you – the wp-config.php file is like the heart of your WordPress site. It holds all the essential settings that tell WordPress how to function. It’s a bit like the blueprint for your entire website!
But sometimes you need to access and edit this file and that can feel a little intimidating especially if you’re not super comfortable with technical stuff.
Don’t worry though! I’ve recently discovered a super simple method that’s made my life a lot easier.

So what exactly does this file do? Well it’s responsible for connecting your WordPress website to the database.
Think of the database as a massive library where all the information about your website – like posts pages settings and even user data – is stored.
The wp-config.php file acts as the librarian ensuring that WordPress can access and retrieve the information it needs from the database.
This makes it crucial for your website to operate properly.
But that’s not all! This little file has many other important roles:
- Security Keys: It contains unique security keys that help prevent malicious attacks.
- Table Prefixes: You can customize the database table prefixes making your site more secure.
- File Locations: You can relocate the core WordPress folders like wp-plugins wp-uploads and wp-content for better organization and security.
- Advanced Configuration: It lets you tweak all sorts of advanced settings like setting up multisite functionality managing cookie domains and even controlling how WordPress interacts with your database.
Where to Find Your wp-config.php
Now the good news is that finding your wp-config.php file is pretty straightforward:
- Existing WordPress Site: For an already-running site it’s located in the root folder of your WordPress installation. Think of it as the home directory where all your WordPress files reside.
- New WordPress Site: If you’re setting up WordPress for the first time you won’t find it right away. It gets automatically generated during the installation process.
Accessing Your wp-config.php File
You can access your wp-config.php file using two methods:
1. Secure File Transfer Protocol (SFTP)
This is my personal favorite method and it’s pretty user-friendly:
- SFTP Client: First you’ll need an SFTP client. I like using FileZilla but you can choose from plenty of other options. Just download and install one that works for you.
- SFTP Credentials: Now you’ll need to get your SFTP credentials. These are the keys to unlocking your server. You can find them in your hosting control panel. If you can’t locate them don’t hesitate to contact your hosting provider’s support team.
- Connect to Your Server: Open your SFTP client and enter your host’s IP address or URL your SFTP username password and the port number. You may see a “host key unknown” alert. Click “OK” and proceed and if you plan on using your SFTP client again check the “Always trust this host add this key to the cache” box.
- Navigate to Root Directory: Once connected you’ll see a file tree on your screen. Look for a folder named “www” or “public_html.” This is your root folder and it’s where you’ll find wp-config.php.
- Download wp-config.php: Locate the wp-config.php file in the root folder. Right-click on it and select “Download.” You can also drag and drop the file to a folder on your local computer.
2. cPanel’s File Manager
If your web hosting provider offers cPanel you can also access the file manager there:
- Open cPanel: Log in to your cPanel account and navigate to the “Files” section.
- File Manager: Click on “File Manager.”
- Root Folder: Just like with SFTP locate the “www” or “public_html” folder to access your root directory.
- Download wp-config.php: Find the wp-config.php file and right-click on it to select “Download” or single-click the file and click the “Download” option from the top menu.
Editing Your wp-config.php File
Remember always make a backup of your site before you start editing wp-config.php.
It’s like having a safety net in case something goes wrong!
1. Using a Source Code Editor
I highly recommend using a source code editor for editing wp-config.php.
It provides a clean and organized way to work with the code making it much easier to make changes without breaking your website.
- Open wp-config.php: Choose your favorite source code editor (I use Atom.io) and open the downloaded copy of your wp-config.php file.
- Make Edits: Now you’re free to add or modify the information in your wp-config.php file. I’ll explain more about the different edits you can make in a bit.
- Save Your Changes: Once you’ve made all your edits save the file to your local machine.
- Connect to Your Server: Log back into your web server using either SFTP or cPanel.
- Rename Original File: Rename your existing wp-config.php file to something like “wp-config-original.php.” This ensures that you have a copy of the original file just in case something goes wrong with your edits.
- Upload Edited File: Use either SFTP or cPanel to upload your edited wp-config.php file back to your website’s root directory.
- Test Your Website: Visit your website to check that everything is functioning properly. If you see any problems you can easily revert to your original file by renaming it back to “wp-config.php” and deleting “wp-config-original.php.”
2. Editing Directly in cPanel (More Risky)
You can also edit wp-config.php directly in cPanel but I strongly advise against it.
It’s a bit riskier because if your internet connection drops during editing you could lose your changes.
Plus you’re more likely to accidentally overwrite your original file.
However if you’re confident with cPanel and have a reliable internet connection you can follow these steps:
- Find wp-config.php: Log in to your cPanel account and go to the “File Manager.” Navigate to your root folder usually “www” or “public_html.”
- Create a Backup Folder: Click on “+Folder” to create a new folder where you’ll store a backup copy of your wp-config.php file.
- Copy wp-config.php to Backup Folder: Find the wp-config.php file in your root folder and right-click on it to select “Copy.” You’ll be asked to enter the file path for the backup folder. Enter it and click “Copy File(s).”
- Rename Backup File: Go to your backup folder and rename the copied wp-config.php file to something like “wp-config-original.php.”
- Edit Original wp-config.php: Navigate back to your root folder and open wp-config.php using the “Edit” option in the File Manager menu.
- Make Changes: Edit the file as needed.
- Save Your Changes: Save the file in cPanel.
Manually Creating wp-config.php
If you need to create a wp-config.php file manually you can use the wp-config-sample.php template provided with WordPress:
- Open wp-config-sample.php: Use your source code editor to open the wp-config-sample.php file.
- Enter Database Details: You’ll need to add the following information:
- Database name
- Database username
- Database password
- Database hostname
- Database charset (usually utf8)
- Database collate type (leave it as is if unsure)
- Generate Security Keys: You can use the WordPress.org secret-key service to generate unique security keys.
- Define Table Prefix: You can use a custom table prefix if you’d like.
- Set Debugging Mode: By default debugging should be set to “false” unless you’re developing your site and want to see error messages.
- Add Custom Values: You can add any custom values you need in the commented-out sections of the code.
- Define Absolute Path: Leave this as is unless your WordPress is set up in a subdirectory.
- Save File as wp-config.php: Save your file as “wp-config.php” and upload it to your root folder using SFTP or cPanel.
What Can You Configure via wp-config.php?
The wp-config.php file offers a wide range of customization options:

Troubleshooting
1. Missing wp-config.php File
If you can’t find your wp-config.php file search using your SFTP client or cPanel’s File Manager.
If it’s still not found it might be in a folder with restricted permissions so contact your hosting provider for assistance.
2. Write Permissions Issues
If you see an error message about missing write permissions for wp-config.php it’s probably due to a plugin that needs write access to the file.
Adjust the file permissions via SFTP or cPanel if your host allows it.
3. wp-config-sample.php File
The wp-config-sample.php file is a template that’s included with WordPress.
You can use it to create a wp-config.php file manually.
